Objective Data for Complete Occlusal Analysis

The K7 Evaluation System provides the dental clinician or researcher with three distinctly different technologies for measuring, displaying and storing objective data on physiologic and anatomical status and function. This objective data enhances the doctor’s diagnostic and treatment considerations with information not previously available.

The K7 Evaluation System is supplied in a compact housing that can be plugged in to the serial port of virtually any PC type computer, desktop or laptop. Small and portable, the unit and its peripheral apparatus can be quickly stored in the provided protective case for ease of transportation. Windows based software simplifies operation and color graphics make it easy to distinguish overlapping data from multiple channels and to print attractive reports for patient education, insurance or referring doctors.

For over thirty years, Myotronics has been dedicated to strong customer support. One small example is "Kevin's Pearls". Registered owners of K6-I or K7 Evaluation Systems can have helpful users tips sent by e-mail every week. These tips from our head programming engineer aid customers in deriving maximum benefits from their instruments.

A number of useful testing protocols referred to as "Scans" are pre-programmed for the convenience of the user. Additional custom protocols may be programmed by the user to fulfill unique needs or preferences. The three individual modules and their capabilities are listed below.

K7/CMS Computerized Mandibular Scanner (CMS - Jaw Tracking)

Multiple sensors in an extremely light weight (four ounce) spectacle-like array, track the motion of a tiny magnet attached to the lower incisal gingiva with adhesive material. The configuration is totally non-invasive and, unlike clutches, does not interfere with patient function. The opposing sensors are wide apart permitting unobstructed access to the oral cavity for taking bite registrations and other clinical procedures, and the system is virtually immune from effects of slight head motion or nearby metallic or electronic interference. A patient education mode is included to simplify patient understanding and staff training.

These scans are invaluable three dimensional representation of mandibular rest, the relaxed neuromuscular path of closure, centric occlusion, habitual path of closure and protrusive guidance that allows the clinician to record an optimal occlusal position.

K7/EMG Eight Channel Electromyograph (EMG)

Utilizing high quality bipolar surface electrodes, EMG data can be taken from up to eight muscle sites simultaneously and in real time. The program permits taking electromyography data either at rest or in function. All eight channels may be displayed simultaneously, for a period of 15 seconds (one visual screen width). The K7/EMG signal processing circuitry provides unsurpassed protection against system noise or motion artifact. The patient education mode permits quick and easy patient education as to status of masticatory muscles.

These scans provide an objective measurement of masticatory muscle electrical activity which accurately represents the physiologic state of rest.

Model K7/ESG Electrosonograph (ESG)

TMJ Vibration (Sound) Evaluation System. A lightweight headset holds highly sensitive vibration transducers over each TM joint, enabling simultaneous, bilateral capture of tissue vibrations emanating from joint sounds. Vibration (sound) data is correlated to vertical dimension of opening and closing, providing clinicians with valuable information to aid in assessing the status of articular disk and joint function.

The ESG includes the ability to document TM joint status through recording joint sound vibrations – simply and non-invasively.
